  d. 1, 2, and 3 only

Question 2

Which of the following can occur with excessive pulmonary artery catheter movement?
 
  a. Catheter whip
  b. Balloon rupture
  c. Catheter knotting
  d. Dampened waveform

Answer to Question 1

ANS: B
The reason the antecubital and femoral veins are not appropriate for the insertion for this patient is because one of the common problems associated with these sites is phlebitis. Using either of these sites in a patient who already has phlebitis would put the patient at risk for worsening the patient's condition.

Answer to Question 2

ANS: C
Excessive catheter movement can cause catheter knotting. Catheter whip is caused by high car-diac output or abnormal vessel diameter. Balloon rupture is due to loss of balloon elasticity or overinflation. Dampening of the waveform can be caused by air in line, a clot in the system, kinks in line, a catheter tip against the vessel wall, over-wedging, or blood on the transducer.
